PVT/IQ GNSS scenario simulation
Validate your equipment with realistic, reproducible signals
Why simulate GNSS scenarios?
On-board geolocation systems need to be tested under conditions that are close to the real thing, but controlled and reproducible. The simulation of GNSS scenarios makes it possible to :

- Replay recorded GNSS signals in specific environments (dense urban areas, tunnels, railways, etc.).
- Evaluate positioning performance (PVT: Position, Velocity, Time) in critical contexts.
- Simulate disturbed GNSS signals: loss of satellites, multipath, masking, local interference.
- Compare different configurations of antennas, receivers or GNSS algorithms.
- Reproduce exact use cases in the laboratory, without the hazards of a field campaign.
Our GNSS simulation services
We offer our expertise to design and execute advanced GNSS test scenarios:
- Definition of trajectories and representative environments: urban areas, railways, agriculture, ports, etc.
- Generation of PVT or IQ (in-phase & quadrature) test scenarios, based on real or synthetic signals.
- Simulation of degraded or restrictive GNSS conditions, to validate the behaviour of on-board systems.
- Creation of libraries of tailor-made scenarios, which can be replayed and adapted to the customer's test protocols.
- Use of GNSS simulation benches compliant with EN 16803 standards.
- Integrated statistical analysis: accuracy, integrity, availability, DOP, fix losses, satellite interruptions, etc.
- Performance comparison between receivers, configurations or firmware.
